4 Claims.

This invention relates to a device in the form of a top front end for afulling mill which is movable on the fulling mill itself in a very easymanner to uncover the top rolls to enable them to be re-lagged, turneddown, or dismantled.

The principal other objects of the invention are to provide this topfront end in such a form that it can be fixed to the rest of the frame,very readily detached therefrom with equal facility, held in position onthe fulling mill while repairs are being made, and. set back intoaccurate position with a single motion ready to be fastened in place toput the fulling mill into position for proper operation.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. l is aside view of an ordinary fulling mill showing a preferred form of thisinvention with the top front end drawn back away from the top rolls toexpose them for repair or replacement, and

Fig. 2 is a similar view, showing the top front end brought back intooperative position and fastened to the fulling mill.

Most of the fulling mills in use are equipped with Wood lagged rolls.These very often have to be turned down and also have to be re-lagged.They even have to be taken out and repaired in other ways. Heretofore,it has been necessary entirely to dismantle the top of the mill beforeany of these operations could be performed. The mere dismantling anddisconnecting the parts takes from fifteen to twenty-five hours.

By this invention the rolls can be exposed and can be removed from themachine, if necessary, in approximately one-tenth the time heretoforeoccupied by this machine. Also the demountable front end permits accessto the rolls as they are mounted in the machine. Hence it is nowpossible to re-lag rolls and refinish them right in the machinewithoutdanger of replacing them incorrectly and without the necessity ofremoving them.. Incidentally also either one of the rolls can berepaired or removed without disturbing the other roll which is adistinct advantage. If there are any other repairs necessary to themetal work of the roll, it can be accomplished more easily.

In the form in which the invention is illustrated, an ordinary fullingmill I0 is employed having the top rolls H and I2 supported on bracketsl3 and [4 at both ends. These brackets are secured to the framework atone end, they assignors to Rodney Mass, acor- 1938, Serial No. 183,089

carry the axles of the rolls and at the other end they are secured, asshown in Fig. 2, to the demountable top front end I5 when the machine isin use, as shown-in Fig. 2.

The frame of the machine is provided with a platform l6 located in.permanent position and extending out to the front of the machine. Thismay be supported by struts ll or vertical supports H8 or both, as shown.This platform furnishes a track for two pairs of rollers H! on thebottom of the end [5. Also on the body of the frame of the fulling millID are located tracks 28, preferably convex in cross section for therollers 19 which, preferably, are grooved rollers. This track isprovided with two notches 2i and, of course, there is such a track oneach side of the machine.

When it is desired to re-lag, repair, or remove one or both of the rollsH and 12, the fastening devices are removed from the brackets 13 or I4and the end I5 is moved back. Of course, the first action is to lift therollers l9 out of the notches 2| and this is ordinarily done by a pinchbar. The end is then rolled on the platform IS, the repairs made, theend I5 moved back where the rollers 19 sink into the notches 2|. Thesenotches not only serve to prevent the end Hi from rolling again beforeit is fastened but they serve as the supports for it.

It will be noticed that the end l5 has a horizontal projection at 23 ateach end which, when the parts are in operative position, passes over acomplementary projection 24 on each side of the fulling mill. It is notintended that these surfaces constitute a rest to take away any of theweight of the ends.

In this way it will be'seen that this demountable front end is adistinct saving because, after the machine is erected, the front enddoes not have to be dismantled, as has been the case here: tofore. Itcan be moved simply as a unit. Furthermore, the customer can quicklyerect it in his mill, which is a direct saving in labor and eliminatesthe need of adjustments. Otherwise adjustments are made at the factoryat the time of the first erection. The moving of this end back as shownin Fig. 1 leaves the operator full access to the rolls and any operationdesired can be performed on them, often without moving them at all andavoiding the necessity of taking down the whole equipment,

Having thus described our invention and the advantages thereof we do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what we claim is:

1. As an article of manufacture, a fulling mill having a pair of rollsat the top one over the other and provided with a detachable top frontend covering the side surface of these rolls and capable of being movedbodily away from them horizontally to expose them for repairs ordismantling.

2. In a fulling mill, the combination with rolls, of a top front endadapted to cover said rolls and detachable therefrom, a platform beyondthe end of the fulling mill and supporting rollers on the top front endby which the latter can be moved from normal position horizontally onthe platform to expose said rolls.

3. In a fulling mill, the combination with the rolls, of a top front endnormally covering them, detachable means for fastening the front end inposition to cover the rolls, a platform for receiving the top front end,rollers for supporting the top front end on the platform, and tracks onthe fulling mill fitting said rolls and having recesses into which therollers will sink when the top front end is moved up to operativeposition and which will prevent said end from moving while beingfastened in place.

4. In a fulling mill, the combination of a top front end, a platform forreceiving the top front end, rollers for supporting the top front end onthe platform, and tracks on the fulling mill having recesses into whichthe rollers will sink when the top front end is moved up to operativeposition and which will prevent said end from moving while beingfastened in place.
